New formulae for the Aharonov-Bohm wave operators

S. Richard

It is proved that the wave operators corresponding to Schroedinger operators with Aharonov-Bohm type magnetic fields can be rewritten in terms of explicit functions of the generato…

The method of the weakly conjugate operator: Extensions and applications to operators on graphs and groups

M. Mantoiu, S. Richard, R. Tiedra de Aldecoa

In this review we present some recent extensions of the method of the weakly conjugate operator. We illustrate these developments through examples of operators on graphs and groups…

Hochschild Homology and Cohomology of Klein Surfaces

Frédéric Butin

Within the framework of deformation quantization, a first step towards the study of star-products is the calculation of Hochschild cohomology. The aim of this article is precisely…

Two phase partially miscible flow and transport modeling in porous media: application to gas migration in a nuclear waste repository

Alain Bourgeat, Mladen Jurak, Farid Smaï

We derive a compositional compressible two-phase, liquid and gas, flow model for numerical simulations of hydrogen migration in deep geological repository for radioactive waste. Th…

Bi-Hamiltonian nature of the equation

Valentin Ovsienko

We study non-linear integrable partial differential equations naturally arising as bi-Hamiltonian Euler equations related to the looped cotangent Virasoro algebra. This infinite-di…

-Uniqueness of Generalized SCHRÖdinger Operators

Ludovic Dan Lemle

The main purpose of this paper is to show that the generalized Schrödinger operator , , is a pre-generator for which we can…
